Bangkok's controversial new cable-stayed Rama VIII bridge opened for traffic this week. Spanning the Chao Phraya River, the £45M structure comprises a 475m long steel plate girder and reinforced concrete deck, supported by a 161m high reinforced concrete pylon. The deck is protected by a glass fibre reinforced modular enclosure system, developed by FaberMaunsell, but designed and installed locally.
FaberMaunsell had raised concerns that the local firm used would lack the expertise to use the system safely (NCE 28 March). But Bangkok Metropolitan Administration engineer Mott MacDonald is satisfied with the enclosure design. Mott MacDonald, which acts as engineer to the client, was responsible for conceptual design, procurement advice and construction supervision.
